Thanks for reporting this issue. This is the way Unix permissions work, and is to be expected. The first user you have created in both installations have the same User ID (uid). They are considered the same user permissions-wise.
If you want to prevent one installation from seeing data in the other, you need to create new users with a unique UID, or use home directory encryption that is offered during installation. Closing this bug as it isn't an issue. Thanks. ** Visibility changed to: Public ** This bug is no longer flagged as a security vulnerability ** Changed in: nautilus (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in ubuntu. https://bugs.launchpad.net/bugs/723212 Title: I can see the files in the home folder of another user in which I made a chmod 0700 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
